Wind Power in India has been wildly successful and is the 5th biggest in the world because of substantial incentives from the government. One of them has been accelerated depreciation which has made hundreds of companies and rich individuals buy small wind farms. This helps them offset their tax liabilities providing a substantial 2 digit returns. However the big drawback in this from of green subsidy is that it does not incentivize the production of wind energy. Once the wind farm is set up, the incentive to produce lots of electricity is not there unlike the case of Feed in Tariff where your returns are solely based on the electricity generation.
